Such demagoguery helps explain why more than 100 Republican national security experts signed a letter denouncing Trump last spring, citing a vision of American power that is “wildly inconsistent and unmoored in principle”; and why last month 50 Republicans, including former Cabinet officials and two former heads of the Department of Homeland Security, signed a letter predicting that Trump would be “the most reckless president in American history.” Those sentiments were recently seconded by lifelong Republican Robert Gates, the former secretary of defense and director of the CIA, who in a scathing Wall Street Journal op-ed called Trump “beyond repair” and someone who would be a “thin-skinned, temperamental, shoot-from-the-hip and lip, uninformed commander-in-chief” and “too great a risk for America.”
In private emails hacked and leaked to the press, Colin Powell, former secretary of state and chairman of the Joint Chiefs, called Trump a "national disgrace and an international pariah" and Flynn “right-wing nutty” for empowering him. "Flynn got fired as head of DIA. … I asked why Flynn got fired. Abusive with staff, didn't listen, worked against policy, bad management, etc. He has been and was right-wing nutty every [sic] since,” Powell wrote, later wondering "how [Flynn] got that far in the Army?"
To counter that withering criticism from Republican ranks, the Trump campaign released a letter signed by 88 former generals and admirals supporting his candidacy and arguing that it represents a “long-overdue course correction in our national security posture and policy.” Many see the hand of Flynn, who was earlier vetted as a possible vice president on the Trump ticket.
